SENSIBLE HEAT & LATENT HEAT

SENSIBLE HEAT Sensible heat produces a rise or fall in temperature of substance Sensible heat does not change physical state of substance LATENT HEAT Latent heat changes the state of substance i.e. Liquid to Gas, Solid to Liquid and Liquid to Solid in case of boiler . Latent heat does not cause temperature change in the substance

Why spirals are provided at the Idustrial Boiler Chimney

Chimney:- Chimney , as we know, is used to reject the flue gases to the atmosphere, coming from the Steam Boiler during operation. Also, it is a megastructure in Steam Boiler assembly and any discrepancy in its structural and foundation work can cause extremely serious damages, may even lead to casualties or plant shut off till its re-erection. The designer must consider all the factors while designing chimneys and one of the major factors amongst them is the wind factor. Blowing wind tries to overcome its static inertia but fails, if spirals are provided on the surface of the chimney. BUT THE QUESTION IS HOW????? Consider a chimneys (without spiral wings) , when the blowing wind comes in contact with its upstream surface, stagnation point (zero velocity) is achieved at that point i.e. pressure generated is high at that point and at the downstream end a vacuum is created as the wind coming in contact with the chimneys , gets deflected and meets after some point (wake regio...

What is Mobrey

What is Mobrey? Mobrey is the name used for the Automatic water level controller , it comes under the category of mountings and fittings of Steam Boiler Assembly . As the name suggests, it is used for maintaining the water level in the Boiler shell. It is mostly used in smoke tube steam boilers not in water tube boilers , as the shell diameter of the former is greater than that of latter irrespective of their running capacities and working pressures. We at Thermodyne Boilers had supplied and installed successfully these Mobrey (automatic water level controllers) to all our clients. For smoke tube boilers , mobrey is fitted externally on the nozzles coming out of the s team boiler shell curvature. It consists of a hollow cylindrical unit in which a float hangs. So, when the feed pump works, it supplies feed water to the boiler shell and it gets filled up. From those nozzles, the water also enters the hollow cylin...
